Trademark represents the good image of an enterprise and the rich cultural heritage of an enterprise. It can always stimulate consumers' desire to buy goods all the time. Consumers' strong desire for Apple, Nike, etc. does not value the so-called product quality, but the brand image they possess. Having a good trademark is the prerequisite for a company to have a good brand image! With a good trademark, companies must not only maximize the role of the trademark, but also protect its safety at all times. In this era of rapid development of network technology, people have moved shopping malls, restaurants and other physical objects onto the Internet stage. For an enterprise, this is an opportunity that presents both opportunities and challenges. On Taobao, an online shopping platform with more than 10 million daily views, more and more companies have registered their own flagship stores, and companies are using their brand advantages to seek greater benefits for themselves. However, trademark infringement incidents also occur from time to time. When a company's trademark is illegally appropriated by others, the losses caused to the company are immeasurable. When consumers purchase fake products, they do not think about whether the trademark has been stolen, but they doubt their good impression of the product and the company in the past, which in turn reduces their favorable impression of the product and the company. When infringement incidents continue to occur, consumers will choose not to purchase any products from this company, and the good brand image that this company has worked so hard to create will be destroyed. Therefore, if you have a good trademark and a good brand image, you must not only maximize their role, but also know how to protect it!
